2.2 Function
Air is filtered inside the modules by HEPA filters and supplied into space through the air nozzles
located in the front panel of the unit.
The circumferential supply airflow from the supply air unit is directed partly towards the operating
area and partly towards the room periphery. The inward supply airflow displaces the contamination
generated in the operating area and prevents the intrusion of the outward supply airflow into the
centre. The fine-tuning of the throw pattern is carried out by Halton.
The supply unit size and airflow pattern adjustment are optimised by Halton based on the end-user
requirements and specifications.

3.2.4 Installing the ceiling system
This installation step is optional. The supply and installation of a ceiling system is the responsibility of
the customer.
The Halton Vita VSN supply air unit is compatible with the T24 T-bar false ceiling systems.
The T-bar runners are installed below the device. The unit is designed to fit in the standard size of
the false ceiling grid.
NOTE: For the design of Halton Vita VSN units that are compatible with a different false ceiling
system, contact Halton Sales.
Install the main runners parallel to the unit. The runners can be slid in the gap between the modules
for a uniform installation. Main runners must have a groove distance that is divisible by 100 mm to
support this method, in order to have grid dimensions that match the unit dimensions.
3.2.5 Installing the HEPA filters
Before you start
Make sure that:
•
•
•
•
•
•
All the site works that produces dust and dirt are completed.
All non- essential items are removed from the operating room.
The operating room is clean.
The ventilation system is tested.
The amount of air and temperature regulation is tested.
The air channels are cleaned or properly flushed.
CAUTION!
Use extreme caution while fitting the filters. Installation of the filters should be performed by
trained personnel. The slightest damage to the filter medium can result in a leaking filter.
Procedure
1. Check that challenge ports can be located for the filter leakage test.
Every standard duct connection in Halton Vita VSN has two upstream aerosol challenge
measuring ports. This allows you to measure of the aerosol concentration and to verify that
the mixing is homogenous.
Version 4.0
All rights reserved © Halton
Halton Vita VSN - Installation and maintenance guide
19(31)
Make sure that the upstream challenge injection port is located far enough. The position has
to allow mixing of test particles within the air duct. When injecting the test aerosol, ensure
that the concentration of the test aerosol is even across the back of the whole filter.
2. Remove possible dust protection and front panels.
NOTE: See Removing the Halton Vita VSN front panels for detailed instructions.
CAUTION!
Store the front panels in a safe and clean place during the HEPA filters installation.
3. Remove the filter brackets and clean the interior surfaces and frame components with a
disinfectant.
Version 4.0
All rights reserved © Halton
Halton Vita VSN - Installation and maintenance guide
4. Fit the filter inside the module.
5. Fit the rest of the filters in the same manner as the first one.
6. Secure the filters with the filter brackets.
CAUTION!
While tightening the filter brackets, take care no to damage the threads.

dirt and dust accumulation.
Perform an installed filter system leakage test according to the ISO 14644-3 Cleanrooms and
associated controlled environments standard.
3.2.6 Installing Halton Vita VSN front panels
Procedure
1. Starting from the outside corner of the unit, fit the front panel inside the module.
2. Push-in the front panel using the tool. There are two openings on the side of the front panel.
3. Install the rest of the front panels in the same manner as the first one.

4 Maintenance
4.1 Maintenance schedule
The required servicing tasks include filter change and cleaning the unit. Determining the cleaning
frequency is the responsibility of the customer.
To ensure that air quality meets the requirements check the HEPA filter in regular time intervals and
replace the filter when necessary. The servicing frequency of a filter depends on the air cleanliness
of the supply air and room air. Replace the filter immediately if:
•
•
•
the final differential pressure has been reached
filters have been contaminated, or there is visible growth on the filter media
the particle count has been exceeded (filter is damaged)
4.2 Step by step instructions
4.2.1 Removing the Halton Vita VSN front panels
Procedure
1. Starting from the outside corner of the unit, open the front panel. There are two openings
on the side of the front panel. Pushing and release with the tool.
2. Remove the first front panel.
